Update Capslock configuration to cover all packages

After adding Capslock in 6873167 the
project was split into multiple `package`s to separate the library from
the CLI in 6e9bb3c. This change caused
a loss of coverage by Capslock which, by default, only reports on the
capabilities of the current `package`. Thus, prior to this change, it
missed the package in `./cmd/ades` (hence the large number of lines
removed in the latter referenced commit).

This fixes that leveraging Capslock's `-packages` flag which support the
standard Go './...' syntax to cover all packages under the current dir.
